The specific rotation, [a]p, for sucrose is +67. What is the observed rotation for a solution of 0.40 g of sucrose in 10 mL of water in a sample tube having a pathlength of 10 cm? degrees. The observed rotation of a solution of 1.2 g of a compound in 10 mL of water is +1.3 degrees. If the pathlength is 10 cm, what is the specific rotation of the compound?
